According to recent updates from the U.S. District Court for the District of New Jersey, lawsuit trials for Invokana are slated to start in September of this year.


If you or someone you love has suffered side effects, e.g. an amputation, kidney damage, and/or ketoacidosis from diabetes drug Invokana, contact the Invokana attorneys at the Mindiola Law Firm to discuss your legal rights now.

What is Invokana?

Invokana is a prescription medicine used in the treatment of Type 2 diabetes (T2). Recent studies show that patients taking Invokana and/or other prescription medications that contain canagliflozin, e.g. Invokamet, are at significantly higher risks of suffering lower limb amputations.


As a result, more than 1,100 lawsuits have been filed against the manufacturer of these drugs, Janssen Pharmaceuticals. Janssen is a division of the giant pharmaceutical company, Johnson & Johnson.

What are the Known Side Effects of Taking Invokana?

Some patients who were prescribed Invokana or Invokamet (canagliflozin) for their diabetes saw severe or fatal side effects, such as:


  1. Lower body amputation. Diabetes may cause some individuals to experience poor circulation, peripheral arterial disease, and/or nerve damage. Some diabetic individuals may require a partial or total amputation. An FDA study showed that patients taking Invokana needed foot or leg amputations about twice as often as others taking a placebo.
  2. Diabetic ketoacidosis. Some diabetics experience a life-threatening complication when higher levels of ketones, a type of blood acid, enter the bloodstream. Diabetic ketoacidosis is a health emergency: it may cause brain swelling, dehydration, coma, or death.
  3. Acute pancreatitis. Patients using Invokana may experience a sudden pancreatic inflammation. The pancreas produces hormones in the body, including insulin. Medical researchers note that acute pancreatitis can lead to many additional health problems for the patient, including death.
  4. Kidney failure. FDA reports (2016) show that Invokana patients have a much higher risk of renal failure, or severe kidney damage. It may be necessary for these patients to undergo dialysis treatments and/or hospitalization. Invokana patients with existing kidney disease are at even higher risk when using it.
  5. Heart disease. Invokana patients are also a higher risk of cardiovascular problems. Eight out of 15 panelists on the FDA approval board voice concerns over cardiovascular risks of this drug.


In addition, Invokana patients experience the following additional side effects, including:

  • Fatigue
  • Abdominal pain or tenderness
  • Bone fractures
  • Allergic reactions
  • Constipation
  • Falls
  • Dehydration
  • Hyperkalemia, or higher than normal levels of potassium in the body
  • Increased cholesterol
  • Hypersensitivity reactions
  • Increased urination
  • Low blood sugar
  • Kidney problems
  • Nausea
  • Low blood pressure
  • Urinary tract infections (UTIs)
  • Vaginal itching
  • Urinary discomfort

Why Are Some Patients Filing Invokana Lawsuits?

According to the Johnson & Johnson Q3 report, more than 1,100 people have filed Invokana lawsuits.


Although many reviewers initially believed that SGLT2 drugs would significantly improve the quality of life for T2 diabetics, it soon became clear that Invokana and similar drugs have hidden dangers that require label warnings and additional study.


More people taking Invokana are becoming ill or, in some instances, passing away.


Today, patients are filing claims that allege Janssen should’ve told patients about the risks of taking Invokana.


CANVAS/CANVAS-R studies (referenced by the FDA) state that Janssen should’ve taken greater care to warn physicians and consumers about Invokana risks.


Unfortunately, Johnson & Johnson’s subsidiary continued to advertise Invokana as safe for people with diabetes. It was even promoted for additional “off-label” uses, e.g. treating overweight or obesity, reducing blood pressure, or improving cardiovascular function.


Invokana legal claims state that many patients wouldn’t have used Invokana if they’d been told about the higher risks of amputation. Because Janssen and Johnson & Johnson didn’t offer proper warnings, patients couldn’t make informed decisions about whether Invokana was right for them.


Other legal complaints focus on other serious Invokana side effects, e.g. ketoacidosis, serious UTIs, bone fractures and/or kidney (renal) failure.

Do Invokana Patients Claim Mental and Physical Suffering?



Those experiencing severe Invokana side effects claim that taking the drug created more pain and suffering—in addition to the manufacturer’s warnings and/or marketing materials.


While the level of suffering may differ between patients, e.g. ketoacidosis, renal disease, or amputation, Invokana is the common link that created or exacerbated the patients’ conditions.


Some patients claim that, in addition to physical ailments and pain caused by taking Invokana, they suffered mental suffering as well.


For instance, a patient suffering an amputation may experience a range of psychological ailments, e.g. depression, post-traumatic stress disorder (PTSD) or phantom limb syndrome. These patients’ mental health conditions were directly attributable to taking Invokana.

Do Invokana Patients Seek to Recover Medical Costs?



Along with seeking recovery for patients’ mental and physical suffering, those filing Invokana claims seek to recover medical bills and related costs, e.g. hospitalization, surgical procedures, post-op care, and future medical needs (travel to specialists, lodging costs, and expenses that aren’t covered by the patients’ insurance).


Patients or heirs filing Invokana lawsuits may include costs the victims wouldn’t have paid. For instance, a patient who passed away from the complications of Invokana may leave loved ones. Family members may seek burial and/or funeral expenses plus lost earnings the loved one may have earned in the future.

Additional questions

What is an SGLT2 Inhibitor?

Invokana is a type of drug that’s known as an SGLT2 inhibitor. SGLT2 inhibitors block sugar in the patient’s body to prevent its absorption by the bloodstream.


Canagliflozin, Invokana’s active ingredient, is one of four FDA-approved SGLT2 inhibitors in the United States. Other SGLT2 drugs are used outside of the U.S.

How Do SGLT2 Inhibitors Work?

Invokana and other drugs in the SGLT2 class work by preventing the sodium-glucose co-transporter 2 protein (SGLT2) from entering the patient’s bloodstream.


SGLT2 inhibitors stop the process of reabsorption from taking place. The process usually occurs in the patient’s kidneys but, in Invokana patients, the glucose is excreted in the urine instead.


SGLT2 inhibitors like Invokana are prescribed to patients along with a low-carbohydrate diet and exercise. These drugs aren’t intended to control diabetes without the patient making lifestyle changes.


Invokana isn’t effective against Type 1, Type 1.5 or so-called Type 3 diabetes (Alzheimer’s disease). Only T2 diabetics are intended to use Invokana and SGLT2 drugs.

What Other SGLT2 Drugs Are FDA-Approved?

  • Canagliflozin (brand names Invokana, Invokament, and Sulisent) are manufactured by Janssen Pharmaceuticals and Mitsubishi Tanabe Pharma.
  • Dapagliflozin (brand names Farxiga in the U.S., Forxiga in Europe, or Xigduo XR in China) are manufactured by Bristol-Myers Squibb and AstraZeneca.
  • Emphagliflozin (brand name Jardiance) is manufactured by Boehringer Ingelheim and Eli Lilly and Company.
  • Ertugliflozin (brand name Steglatro) is manufactured by Merck and Pfizer.


Other SGLT2 prescription medications are used in other countries. The four drugs listed above are U.S. Food and Drug Administration (FDA) approved.
